speed of light

Definitions

1. The speed of electromagnetic radiation, which in a perfect vacuum is equivalent to 299,792,458 metres per second.
2. A very rapid speed.
   colloquial, figuratively
3. A rate of travel of a signal equal to one cell per generation, the fastest possible speed in the Moore and von Neumann neighborhoods.

Examples

“Early physicists developed insightful methods for measuring the speed⟳ of light⟳.”

“As the subjective speed⟳ of light⟳ is raised within the field, objects outside will appear⟳ to red-shift, eventually becoming visible only to radio telescope antennae.”

“The science world was left in shock⟳ when workers at the world's largest physics lab announced they had recorded subatomic particles travelling faster than the speed⟳ of light⟳ – a feat that Einstein said was impossible.”

“When her cat figured out that a trip⟳ to the vet was in the offing, he took off towards the closet at the speed⟳ of light⟳.”

“In a single generation, a cell can only influence⟳ its nearest neighbours, and so the speed⟳ of light⟳ (by analogy with the speed⟳ of light⟳ in physics) is the maximum rate at which information can propagate.”

“The translated distance divided by the period is the speed⟳ of the spaceship. Since the maximum speed⟳ of propagation of a signal in Life is one cell per generation, this speed⟳ is known as c (the speed⟳ of light⟳). This speed⟳ is also the fastest possible growth of any finite object for a finite number⟳ of generations (think⟳ of a long line of ON cells). However, growth (or even just movement) of a finite object for an infinite time cannot occur⟳ at this speed⟳.”
